SAFETY DEVICE.

Specification of Letters Patent.

Patented Feb. 11, 1908.

Application filed April 2'7. 1907. Serial No. 370642- To all whom it may concern:

Be it known that I, LUDWIG LIPTAI, a subject of the King of Hungary, and resident of the city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Safety Devices, of which the following is a specification.

The present invention relates to safety devices in rolling stock for railroads, and has for its object the provision of means for retaining the rolling stock on the road-bed in case of derailment and preventing it from falling down embankments, etc.

A further object of the invention consists in means for automatically applying the brakes and shutting off the steam or electricity from the car in case of accident.

The invention consists of a substantially vertical frame extending below the truck nearly to the level of the rails. This frame is slidable and by means of a segment controls a holding means for an anchor, supported below the truck of the car, while suitable connections are made with the frame for controlling the brake devices and the supply of power to the train or the car. I

The drawings illustrate the invention in one of its forms, and Figure 1 is a side elevation of a railroad car, showing the safety device-applied thereto, Fig. 2 is a vertical end view of the car illustrated in Fig. 1,Fig. 3 is a detail of construction, and Fig. 4 a side view of a modification.

1 in Figs. 1 and 2 indicates a railroad car of the usual type, 2 is the railroad track and 3 the car wheels. At a convenient point of the truck, a pair of brackets 4 are secured to the truck of the car, and having slidably connected thereto a frame 5. Should for any reason the distance between the rails and the truck become less than the normal distance when the car wheels are on the track, the frame 5 comes in contact with either of the rails of the track and is pushed upward, while a rack 6 of the frame and in mesh with the geared segment 7, causes the operation of a bellcrank 8 and the disengagement of a looking bolt or similar device 9.

An anchor 10 of suitable dimensions is provided below the truck of the car in bearings 11 in such a way, that the withdrawal of the bolt 9 causes the anchor to drop by its own weight, whereby its prongs enter the road bed, engaging the sleepers therein and preventin the falling or sliding off of the car from tl ie road bed.

In order toprevent the breakage of the holding means of the anchor, a resllient device 12, comprising a helical spring, may be interposed between the anchor 10 and its holdin means. The frame 5, in being pushe upward in case of an accident, causes the operation of the valve 13 of the brake system of the car or train, so that the brakes are immediately set. Another similar device 14 may be used to out off steam or electricity from the motor, driving the train or car, so that the danger to the train is considerably diminished.

Fig. 4 shows a modification of the invention, consistin of an inclosure or box 1., located below t e truck of the car; this box is provided with a hinged door 16, having a ock 17', which may be operated by withdrawing the bolt 9 by means of the bellcrank 8, as hereinbefore stated.

As new and useful is claimed and desired to be secured by Letters Patent of the United States:

1. A railroad car having a safety device, comprising an anchor resiliently connected to the car, and means adapted to release said anchor in case the-car leaves the track.

2. A railroad car having a safety device, comprising an anchor resiliently connected to the car, a slidable frame having a rack, a

eared segment in mesh with said rack, and

oldin means for said anchor and controlled by sai segment. 3. A railroad car driven by a source of power and having suitable brakes, a safety device, comprising an anchor resiliently connected to the car, a slidable frame, means on said frame adapted to release said anchor, and means operated by said frame in case the car leaves the track for shutting off said source of power and brakes.

Signed at New York, in the county of New York and State of New York this 24th day of April, 1907.

LUDWIG LIPTAI.
